Letters Patent No. 75,314, dated March 10, 1868.

MPROVED MODE OF S-EGURING THB ENDS 0F FELLOES AND SPOKES IN CARRIAGE-WHEELS.

TO ALL TO WHO THESE PRESENTS SHALL COME:

Be it known that I, JOHN SWITZER, of Lynn, in the county of Essex, and State of Massachusetts, have invented a'new and useful Improvement in the Mode of Securing the Ends of Fellocs and Spokes in Carriage- Whecls; and do hereby declare the following tcbe a full, clear, and exact description thereof, due reference bcinghadto the accompanying drawings,makingpart of this specification, ,and in which- Figure 1 is' a longitudinal section, and

Figure l2 a transverse and radial section of a portion cf the Wheel of van ordinary travelling-vehicle consti-acted in accordance with my invention.-

Figure 3 is a perspective view of the metallic clasp or socket-plate, comprising the subject of myinvention.

This invention `is an improvement in thatmode of connecting the` ends of the fellees and the spokes in carriage-wheels, in which a metallic block or socket-plate is employed for receiving and securing the ends of the felloes, and two or more of the tenons of the spokes, the object of the invention being to provide greater security -againstrseparation of felloes and tire, o rvbreaking away of parts, as well as to expedite the construction and finish of the wheel. v

The invention consists in a metallic block or clasp, having a central tapering hole made through it for reception of the spoke-tenen, and with enclosures upon each end for reception of `the ends of the felices, the outer focusof such enclosures being open, and covered (as well as the outer end c'f the central hole) by the tire, when applied to them as hereinafter explained. l A

In the drawings above referred to, as making part of this specification, A denotes a portion or outer end of one spoke of an ordinary light ,pleasure-carriage Wheel, and a is its tenen, the adjacent ends of its two fclloes being shown at B B, the tire of the wheel being shown at D. The socket-plate, to which reference has been made above,` is shown at E as an elongated metallicibloek, having a tapering cylindrical hole, a, made centrally and radially through it, for reception of the spoke-tenona, the diameter of such hole, a, enlarging toward the outer end thereof. Two enclosures or partial sockets, b Z, are formed Within opposite ends of the block E, for reception of the'ends of the felloes B B, ,a she-rt lip, c, being formedupon' each end of the inner face of the block, and extending beyond the enclosures I; b, to overlapy the ends of the felloes, as shown in iig. 1 of the drawings, a bolt, d, being extended through each lip, c, and the end of the felices, and havingL a head countersunk within the tire, a nut, e, being screwed upon the innerfend of the' bolt to confine the whole together. A

`wdge,f, is to bedriven into the outer end of the spoke-tenon a',- which has the effect of expanding such tenen within thesockct a, and eifectuallyA preventing possibility of escape, or loosening of such tenen, the Wedge itself being retained innplace and prevented from starting by the tire D.

The object of making the. hole a and the enclosures b b open to the outside of the block E, isto allow the spolceftenon to beV wedged, and the ends ofthe fclloes to be more easily and perfectly fitted, and the tread" or surface of the whole to he tted or prepared for the tire in a much Imore expeditious and worknlanlike manner than in the method before practised. A considerable portion of the wood of'the felloe is alsbsav'ed intact, which is not thc case if the metal entirely surrounds it. The bolts d d confine the whole very securely together, and provide perfect security against separation of the felices and tire.

What I claim as my invention, and desire to secure by Letters Patent, is-

The improved mode of fastening the ends of the :felloes and the spokes in carriage-wheols-by means ofthe metallic block E, constructed and applied and secured by the bolts al d, as explained.
